3 Claims.

This invention relates to a lamp support in which the base and upright member for supporting the electric socket or other illuminating element holder are made of sheet material such as sheet plastic or sheet metal.

An object of our invention is to provide a lamp base which is relatively inexpensive and easy to manufacture inasmuch as it can be made in one simple sheet bending operation.

A further object of our invention is to provide a lamp which is difficult to tilt because of its unique structural characteristics.

A still further object of our invention is the provision of a lamp which is attractive and lends itself well with modern furniture designs.

In the manufacture of lamps, it has been common practice to form a at base and secure thereto an upright member, at the top of which is positioned a socket for an electric bulb or other type of illuminating device. This has necessitated the manufacture of at least two separate parts, and in a great many instances, the manufacture of several parts which must then be assembled into a unit. This has resulted in the necessity of several different operations requiring time and expense in the manufacture of lamps. In producing lamps in accordance with our invention, the article is made in one molding or sheet bending operation, thereby resulting in a manufacturing cost which is much less than for lamps made by other methods.

In order that our proposed lamp and method of manufacture thereof may be more easily understood, it will be described in connection with the accompanying drawing, in which Fig. 1 is an elevational View of a lamp made in accordance with our invention;

Fig. 2 is a cross-sectional view taken on the line II-II of Fig. 1;

Fig. 3 is a bottom view of the lamp shown in Fig. 1;

Fig. 4 shows a piece of sheet material shaped suitably for making the lamp shown in Fig. 1;

Fig. 5 is a modification showing the bottom view of a lamp;

Fig. 6 is a further modification showing the bottom view of a lamp;

Fig. 7 shows a piece of sheet material suitable for making the modification shown in Fig. 5; and

Fig. 8 is a modication of our invention showing a candle holder.

In carrying out the preferred embodiment of our invention, a sheet of plastic material such as Bakelite Lucite Vinylite, etc., or metal such as aluminum, stainless steel, etc., shaped in accordance with the design shown in Fig. 4 is convolutely rolled, starting with the side A-B which is rolled around a conventional electric socket. This rolling operation can best be accomplished by using a mat of rubber the same shape as the sheet of material shown in Fig.: 4. lIhis sheet of rubber is preferably very thin along the line A-B and becomes progressively thicker toward the point C. This rubber sheet is placed on the sheet of plastic and the two are rolled simultaneously, starting to roll from the line A-B and rolling toward point C. By reason of the fact that the rubber mat is very thin along the line A-B the distance between the convolute layers is very small at this point, but the distance between these convolute layers becomes progressively greater toward the periphery of the lamp base.

From an examination of Fig. 2 it will be observed that the line B-C of Fig. 4 forms the base of the lamp, all points on the line being in substantially the same planeas shown in Fig. 3. The line A-C is in the form of a helix Wound about the central line A-B.

Fig. 1 shows the completed lamp with the bulb I and switch button II placed at the top of the lamp body I2. A conventional cord for supplying current to the socket I3 is shown at I4.

Fig. 7 shows a sheet of material Suitable for making a modification of our invention. In this embodiment the sheet is folded along the line A-B and a mat shaped in accordance with the portion ABC is placed between the two folded sheets. This mat is relatively thin along the line A--B and becomes progressively thicker toward the point C. A second mat of the same configuration as the first is placed on top of this assembly. The unit is then rolled starting with the line A-B and rolling toward the points C and D. This produces a lamp base having a bottom design in accordance with that shown in Fig. 5.

In the modification shown in Fig. 8 the electric socket I3 is replaced by a candle socket I5. This arrangement makes an attractive Candlestick holder, having the same advantages as those outlined for the electric lamp described herein.

Our invention may be practiced by using several sheets of material similar to the one shown in Fig. 4. When several sheets are used a lamp base is formed having the bottom configuration shown in Fig. 6. These sheets may be secured together by means of an adhesive in the case of plastics, or by means of solder or welding in the oase of metal.

It Will be obvious from the above disclosure that arrips made in accordance with our invention, while being economical to manufacture, are very attractive and lend themselves well with modern modes of interior decoration. Furthermore lamps made in accordance with our invention will not tip over readily inasmuch as each convolute layer of the material forming the support extends the entire distance from the curved helix forming the top of the supportthrough to the base. If the lamp receives a lateral blow, thematerial forming the support has sufficient spring in it to permit the bottom of the base to remain at on the table while the convolute surfaces rearrange themselves to take the blow. After the blow has been spent the lamp will immediately spring back to its original upright position.

While we have illustrated and described certain preferred embodiments of our invention, it will be understood our invention is not so limited but may be otherwise embodied within the scope rof the following claims:

, We claim:

1. A support for an illuminating device, said support comprising bendable sheet material wrapped convolutely about an illuminating element, said convolutions being disposed in a vertical plane so that the bottom edge of all the convolutions lies in the same horizontal plane.

2. A support for an illuminating device, said support comprising a substantially triangularlyshaped sheet of bendable material wrapped convolutely about an illuminating element, the lower edge of said convolutely wrapped sheet forming the base for the lamp and the top edge forming a helix around the support for the illuminating element.

3. A support for an illuminating device said support comprising a substantially triangularlyshaped sheet of bendable material, said sheet of bendable material being bent double forming two triangularly-shaped sheets joined along one side,

said sheet being Wrapped convolutely about an illuminating element, said convolutions decreasing in height from the interior of the support to the exterior, the one series of convolutions decreasing more sharply than the other.
